Plot Progression

1. The Photograph Nobody Claims — An unauthorized X-ray exposes two bodies, and a photograph becomes the focus of hospital speculation. A note and widespread absences turn curiosity into institutional distrust.
2. Trust Under Examination — Yoon-young and Lee Kyung-jin remain at the hospital while others call in sick. Their attempt to test honesty reveals how deeply suspicion has spread.
3. The Disaster Changes Shape — An expected earthquake fails to arrive, but a diastrophism produces enormous sinkholes across Korea. Maggie's Father waits anxiously as the crisis takes an unexpected form.
4. Work Among the Sinkholes — Sung-won gains road-repair work after the national disaster. Rivalries, missing valuables, and suspicion of Kang-sup make the worksite increasingly unstable.
